HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 515,837, dated March 6, 1894.

Application tiled August 23, 1893. l

To sl/Z3 Whom, t may concern: y

Be it known that I, PATRICK J. MULLANEY,

` acitizen of the United States of America, re-

siding at Lafayette, in the county of Tippecanoe and State of Indian a, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification, reference being had therein to the accompanying drawings.

rlhis invention contemplates certain new and useful improvements in hyd ro-carbon burners and it has for its object the production of a simple and inexpensive burner of this class which will insure the thorough intermingling of the oil and steam and prevent carbonization at the point of the burner, or the formation of carbon deposits on the Walls of the furnace, the force of the combined jet beings, arrested before igniting.

To these ends the invention Vconsists of a hydro-carbon burner having areceiving chamber for the oil with which intermingles a cen- -trai concentric jet of steam, a deliector against which the combined oil and steam strike, and an outer concentric outlet for the steam which intermingles with the rst combined jet of oil and steam as the latter leaves the edges of the deliector, whereby the force of the com bined jet is arrested or softened, and carbonizingat the point of detiection is prevented.

The invention also comprises the details of construction, combination and 'arrangement of parts, substantially as hereinafter fully set forth and particularly pointed vout in the claims.

In the accompanying drawingsz-Figure l is a longitudinal sectional view of my im-v proved burner. Fig. 2 is a view of the parts disconnected. Fig. 3 is a perspective View.

YReferring to the drawings, A designates a ring or head open at its ends and having at one end an interiorly threaded iange a, with which engages the threaded portion a of a truncated cone B. The cone is closedat its widened end h and has a central threaded opening b. In the cylindrical portion h2 of this cone adjacent to the thread d', are formed four, more or less, holes or ports h3 which permit steam to pass from the interior of the cone or steam chamber, into the ring A. The cone B has an outer reduced threaded portion Serial No. 483,305. (No model.)

h4 from which the cone is tapered exteriorly to the outer end, as atb. Upon this threaded portion b4 of cone B is iitted a cylindrical section C having an exterior flange d and a forward tapered or cone-like extension d which incloses the'outer tapered portion of cone B. The flange dislocated within the ring or head A, but is not in contact therewith, thus leaving a narrow circular opening d2 for the cutlet of steam from said ring or head.

D is a pipe which is extended through cone B and provided with athreaded end d3 which engages the threaded openiugh of said cone, and to its extended end is connected a steam supply pipe S. That portion of pipe D lccated within the steam-chamber of cone B is provided with six, more or less, ports d4 through which steam passes from said pipe into said chamber. A narrow space or opening d5 between the outer tapered end of cone B and pipe D permits steam to pass out at this point.

In the outer end of pipe D is screwed a spreader or defiector E which is of approximately cone-shape, and from it projects a threaded rod e which engages a corresponding interior thread of pipe D. In this rod e is a series of tapered grooves or passages e' to permit of the passage of steam from the end of pipe D against the tapered face of the deflector.

luto two coincident openings f, f of ring A and section C is screwed the end of an oil supply pipe F which supplies oil by gravity to the oil chamber f2 which is formed by the tapered ends'cf cone B and section C.

The operation of my improved burner is as Vi`olloWs':--Oi1 is supplied through pipe F to chamber f2 and falls against and around the cone B, While steam is admitted from pipe D through the ports thereof into the steam chamber of cone B and out through the ports of the latter into the ring or head A and also out between the pipe D and the end of the cone. The steam at this latter point takes up the oil which is then carried in a state of atomization against the tapered surface of the spreader or deiiector where it intermingles with a new volume of steam passing out from the end of pipe D, which forces the combined steam and oil oft at an angle of about forty- TOO five degrees until it comes in contact with the volume of steam which passes out from the ring or head A. At this point of union the jet is ignited.

The ladvantages of my invention are apparent to those skilled in the art to which it appertains. It will be specially observed that by reason of intermingling the outer volume of steam with the jet` of combined oil and steam justas the latter is ignited the force or blow of the jet is softened and thus I avoid any destructive action on the furnace. An-

` other advantage is that carbonizing atthe point of the burner is prevented as also the formation of carbon deposits on the walls of the furnace. A hydro-carbon burner thus constructed is extremely simple and inexpensive and not liable to readily get out of order or be deranged.

I claim as my inventionl. A hydro-carbon burner having an oil chamber, a steam chamber centrally communicating therewith, an outer concentric steam outlet, and a spreader or defiector against which the jet of the combined oil and steam strikes, said jet being engaged as it leaves said sprayer or deflector by the volume of steam discharged through said outer concentric outlet, substantially as set forth.'

2f A hydro-carbon burner having an oilchamber, a steam-chamber centrally connecting therewith,an outer concentric steam-outlet, a pipe extending from the burner, and a spreader or detlector in the outer end of said pipe against which the jet of combined oil and steam strikes, Said jet being engaged by a volume of steam from the end of said pipe and as it leaves said spreader or detlector also engaged by the volume of steam discharged through said outer concentric outlet, substantially as set forth.

3. A hydro-carbon burner having an inner oil chamber, an outer circular steam outlet, a steam supply pipe and a sprayer or deflector on the outer extended end of said steam supply pipe, the edge of said sprayer or deflector being Within the line of discharge from said outer circular steam outlet, and means for su p` plying oil to said oil chamber, substantially as set forth.

4. In a hydro carbon burner having an outer circular steam outlet and interior oil and steam chambers, a steam su pply-pipe extending outwardly therefrom and having ports communicating with said steam chamber, and a spreader or deflector in the outer end of said steam-pipe having steam-passages from said pipe leading against its tapered face for engaging the jet of combined oil and steam as the latter strikes said spreader or 6o deflector, substantially as set forth. i

5. The herein described hydro carbon burner, comprising the ring or head having a circular opening forming an outerconcen-y tric steam outlet, an inner oil chamber and an interior steam chamber communicating with said ring or head, the steamsupply pipe extending through and communicating with said steam chamber and also extended beyond said oil chamber, the defiector in the outer end of said steam supply pipe having openings for the passage of the steam from said steam supply pipe, said deiiector being on a line with the discharge from said steam and oil chambers and within the line of discharge from said outer concentric steam outlet, substantially as set forth. Y

6. The herein-described improved hydrocarbon burner, comprising the ringer head, having a circular steam outlet, the cone secured therein and having an interior steam chamber communicating with said ring or head, the section having a tapered end corresponding to said cone and forming in connection with the latter an oil chamber, the oil supply pipe opening into said oil chamber, the steam pipe extended through said cone and having ports opening into the steam chamber of said cone, and the spreader or deiiector having a threaded rod fitted in the outer end of said steam pipe and having grooves or passage-ways for the steam from said pipe, substantially as set forth.

7. The herein-described improved hydrocarbon burner, consisting ofr the ring or head having an inner threaded flange and a hole or opening, the cone having a thread engaging said iiange and provided with acentral threaded opening and a forward tapered end and exterior screw thread, the section engaging said latter screw-thread and having a forward tapered end, an exterior flange Vand a hole or opening coincident with said hole or opening in said ring or head, the oil supply pipe extended through both of said holes or openings,the steam pipe extended throught the said central opening ofrsaid cone and having ports therein opening into the latter, and the tapered spreader or deflector having a threaded rod fitted in the end of said pipe and provided with grooves therein, substantially as set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
